A 46-year-old white woman presented with a 2-week history of a slightly pruritic lesion on the flexor muscle of her right forearm. She also complained of occasionalbleeding from the lesion. On further inquiry, she described a history of 10 similar lesions, which had developed one at a time on various areas of her body over the preceding 5 years. Each lesion had completely resolved over a period of months, without any treatment. The patient had no history of contact with animals or plants of any type.
